GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 250,693, dated December13, 1881.

Application filed October 21, 1881. (No model.)

I 0 all whom it may concern Be it known that I, DENNIS F. VAN LIEW, ofAurora, in the county of Kane and State of Illinois, have inventedcertain new and useful Improvements in Grain-Gar Doors, of which thefollowing is a specification.

Myinvention relates to the devices by which the doors of railwaygrain-cars are operatedin the manner set forthin a former patent grantedto me on the 25th day of May, 1880, the same being a reissue of originalLetters Patent dated June 23, 1874.

The invention provides for a cheaper and yet effectual mode of securingthe door and giving it both lateral and radial support.

The invention consists of a metal shoe applied to and clasping the lowerend of' one or both of the radius-bars shown in said prior patent, andreaching out laterally, upward and downward, from the point of pivotingthe bar to the car, the upward extension serving to stiffen theradius-bar, so it will not bend,either from exposure and abuse or underthe weight of the door, while the lower and side extensions make a broadhearing-surface, which acts to prevent any lateral departure by the dooror bar from the vertical plane in which they should move and beretained.

For the better understanding of this and other features of theinvention, reference is hereby made to the accompanying drawings,forming a part of this specification, wherein Figure 1 is an elevationof the interior of a car-side, showing the door partly raised, with itscarrying devices. Fig. 2 is a longitudinal section of the radius-bar andshoe. Figs. 3 and at are cross-sections of Fig. 2 upon the lines 00 wand y g], respectively.

In said drawings, A represents the car-side A, the door-posts; a, theinside lining of the car; 13, the doorway; O, the door itself; D, thefront carrier or radius-bar; D, the back carrier or radius-bar; d, therabbet at front end of the door, to enable it to fit the shoe whenclosed; d, the rabbet at back end of the door, to fit the bracket in andupon which it rests when open; E, the shoe to receive the front end ofthe door when closed; e 0, liftholes; F and F, (in broken lines,) theguide bar and arm by which the door has heretofore been guided whenraised; G, the usual oak supporting-piece for the door when open, towhich the front radius-bar is pivoted; g g, the lower pivots of thebars; m m, half-oval edge castings secured to the top of the door, onwhich castings the lock device rests when the door is closed; and O, awood filling behind the shoe E. Of the figures, etis a flush lift (shownin broken lines) attached to the outside of the door, and 7 a supportfor the back end of the door when open, secured on the girt of the car.

K is the metal shoe, already mentioned. That part of it surrounding thepivot is substantially round exteriorly, and considerably widened andextended beyond the extent necessary to cover the bar. This givesitabroad bearing-surface, so that it will not be likely to injure the woodparts against which it operates, which, however, may be protected by acovering of sheet metal, 1., as illustrated in Fig. 1. The shoe extendsup the bar a considerable portion of the latters length, and incloses somuch of the bar as lies within its own length by being recessed upon itsinner side with a recess in which the bar may fit. This is shown inFigs. 2, 3, and 4. It necessarily results from the application of a shoethus constructed, with the pivot passing through both bar and shoe andclampingthem together, that the bar will"be materially stiffened, andany tendency to lateral displacement by the door prevented, and its useenables me more safely to dispense with the guiding parts F and F, andwith all substitutes for such guides. The shoe has additional advantagesover the guides F and F, in that it materially cheapens the structure,and its influence in steadying the door is carried nearer to the frontend by the radius-bar, and the door is rendered shoes may be applied toeither of the bars or to both, as thought best. Where but one bar isused it should be applied to that one. It can be readily adapted to barsof any size or form.

By employing the shoe described the upsetting the bar'to strengthen itat the pivotal point and the tapering of heavy bars by forging are bothavoided, and thus cast-iron canbe substituted for wrought, much lessweight of metal be used, and the cost of the forging or upsetting besaved.

1 claim- 1. In combination with the radius-bar of a grain-car door, theshoe K, consisting of the upward extension and the widened and ex- 15tended base recessed on the inner side to receive or clasp the bar,whereby the baris stiifened and the door held in its proper verticalplane, substantially as set forth.

2. The combination, with the radius-bar and 20 its pivot, of the shoe K,having the projecting continuous concentric rim or flange surroundingthe pivot, substantially as and for the purpose set forth.
